Hydrostatic Leak Testing

The aPriori Starting Point VPEs define a single machine for this process.

Cost is based on the following formula:

Process Time = Part Thickness * Leak Test Dwell Rate

Process time is the product of the following:

• Part thickness (average thickness as determined by geometry extraction)

• Leak test dwell rate (specified by the cost model variable leakTestDwellRate—36 sec/mm in aPriori Starting Point VPEs)

This time is bounded above and below by the cost model variables leakTestMaxDwellTime and leakTestMinDwellTime. This maximum or minimum time is used for parts whose thickness does not fall within the range defined by the cost model variables leakTestMinThickness and leakTestMaxThickness (16.7-200mm in aPriori Starting Point VPEs).
